The best way to hollow out an egg depends on how you're going to use it. If it's important that the holes be small, you can pierce the egg with a paperclip or push pin and blow out the interior. If the holes can be larger, your task is much easier.
Things You'll Need
Small Hole Method
Step 1: Wash the Eggs
Wash the eggs with warm water and mild dish soap. Rinse and dry thoroughly.
Step 2: Make Small Holes at Each End of the Egg
Hold the egg over the dish. Pierce the larger end of the egg first with the push pin. You may have to twist the push pin to pierce the shell.
Flip the egg around and make a slightly bigger hole in the opposite smaller end. Continue holding the egg over the dish, as the yolk may leak from the hole.
Step 3: Enlarge the Holes
Straighten out a paper clip. Insert the wire into the end of the egg with the larger hole. Move the wire gently around inside the egg to break up the yolk. The goal it to scramble the yolk and white to make it easier to blow them out.
Step 4: Blow Out the Egg
Holding the egg over a bowl, place your mouth over the hole at the small end of the egg and blow until the contents of the egg drain out. Rinse the egg thoroughly until the water runs clear.
Step 5: Decorate
Use glitter and Mod Podge to decorate as desired.
Large Hole Method
Step 1: Pierce the Egg with the Scissors
Using the points of sharp manicure scissors, pierce the small end of the egg. Insert the scissors into the hole and snip a hole in the desired size and shape. Shake the contents into a bowl.
Step 2: Wash the Inside of the Shell
Wash out the inside of the egg with warm soapy water. Dry thoroughly. Decorate as desired.
